Better than listening meditative music from Bach and Hildegard of Bingen to Australian didgeridoo, so good your system/room could be,
It is better to hum... Yes humming is powerful health too affecting the whole body by vibration...

Now for the "skeptics" a scientific study about "humming" power :
Humming (Simple Bhramari Pranayama) as a Stress Buster: A Holter-Based Study to Analyze Heart Rate Variability (HRV) Parameters During Bhramari, Physical Activity, Emotional Stress, and Sleep
https://pmc.ncbi.nlm.nih.gov/articles/PMC10182780/
«Results
Our findings revealed that humming generates the lowest stress index compared to all three other activities (physical activity, emotional stress, and sleep). Several additional HRV parameters also supported the positive impact on the autonomic nervous, equivalent to stress reduction.
Conclusions
Humming (simple Bhramari) can be an effective stress-buster based on the assessment of several HRV parameters during its practice and in comparison with other activities. A regular daily humming routine can help enhance the parasympathetic nervous system and slow down sympathetic activation.»
